Bathyuriscus
Bathyuriscus is an extinct genus of Cambrian trilobite. It was a nektobenthic predatory carnivore. The genus Bathyuriscus is endemic to the shallow seas that surrounded Laurentia. Its major characteristics are a large forward-reaching glabella, pointed pleurae or pleurae with very short spines, and a medium pygidium with well-impressed furrows. Complete specimens have never reached the size of 7 cm predicted by the largest pygidium found. Bathyuriscus is often found with the free cheeks shed, indicating a moulted exoskeleton. An average specimen will in addition have a furrowed glabella, crescent-shaped eyes, be semi-circular in overall body shape, have 7 to 9 thoracic segments, and a length of about 1.5 inches.Etymology
Bathyuriscus is a variation of Bathyurus, originally based on the Ancient Greek βαθύς "deep", oura, "tail", thus, a trilobite with a deep tail.Distribution
Species belonging to Bathyuriscus have been found in the Marjumian of the United States and in the Middle Cambrian of Australia, Canada, Greenland, Mexico, and the United States.
